Docx and .odt with multi-page tables conversion in Java

GroupDocs.Conversion Product Family
1

Hi,
I am currently evaluating GroupDocs for document to PNG conversion.
My converter always use

saveOptions.pageNumber(1);

I found that, when the source document (.doc/.docx/.odt) has a table having number of rows occupying more than one pages I get below exception.

If I reduce the table rows and fit it in a single page, the conversion works.
Can someone please suggest, if there is any option to get it working??

java.lang.ClassCastException: com.groupdocs.conversion.internal.c.a.b.ef cannot be cast to com.groupdocs.conversion.internal.c.a.b.ee

Here is the code which I m running

public void convertToPNG(FileInputStream fis, String fileName) throws Exception {
    ConversionHandler conversionHandler = new ConversionHandler(Utilities.getConfiguration());
    ImageSaveOptions saveOption = new ImageSaveOptions();
    saveOption.setOutputType(OutputType.String);
    saveOption.setConvertFileType(ImageSaveOptions.ImageFileType.PNG);
    saveOption.setPageNumber(1);
    saveOption.setNumPagesToConvert(1);
    List<String> path = conversionHandler.<List<String>>convert(fis, fileName, saveOption);
    path.forEach(System.out::println);
}

I just want PNG output of the first page of the document.
docsdocs.zip (77.9 KB)

There are two word docs in the zip out of which one (good.docx) works and the other (bad.docx) doesn’t.
One more point:
The good.docx works but it generates two PNGs while, as per the code it should generate one.

Please give it a try and let me know what am I missing.
